To all 'whom it may concern:

Be it` known that I, MARION W. PITNER, a citizen ofl the Y United j States, residing at Chicago, inthe county ofCo'ol andState of Illinois, have invented new and useful lmprovements in Generators, of which the folowing is a specification.

This invention relates to generators of the type employed in connection with hydrocarbon heaters or burnersv for vaporizing gasolene or other liquid hydrocarbon fuel.

It is a well known fact that gasolene and analogous hydrocarbon oils contain lacids which are highly injurious to metals, and

that in consequencenot only are the genera-y tors as now generally used injuriously affected by the fuel coming in direct contact with the metal, but there is produced within the generator under the action of the acids a sediment which is extremely liable to clog the outlet or injector oriice of the vaporizer. Furthermore, it has been found that the liquid fuel coming into direct contact with the metal surface ofthe generator, practice becomes highlyV heated, results in an uneven pulsatious vaporization of the fuel and consequently in an irregular, fluxatious feeding of the vapor to the heater or burner. Attempts have been made to cure objectlon by filling the generating chamber with sand, charcoal or the like, or by employing therein wire cable or asbestos cord, these vmethods being objectionable, however, to

the extent that they failed to prevent the hydrocarbon coming into direct contact with the metal with the above noted deleterious results and at the same time oered an objectionable resistance to the movement of the gasolene orvapor, thus retarding its proper flow and causing an irregular, uneven feeding thereof to the burners and at the same timel necessitating the employment of an increased amountof pressure for forcing the fuel through the generator.

The present invention, which comprehends lining the chamber with a non-combustible material of a nature to resist the deleterious action of the acids in question, has for its objects to provide a comparatively simple,` inexpensive lining which may be readily applied for use, one.V whereby direct contact of therfuel with the innervrmetal wallsl of the chanber is obviated, thus'preventing the formation of a sedimentwithin the generator, and one whereby a gradually uniform which in.

this latter heating` of the interior of the vaporizer is in-A sured, thus insuring uniform conversion of the fuel into, and an even flow of vaporto the burnen vfith these and other objects in view, the invention comprises the novel features, of construction and combination of parts more fully hereinafter described and particularly pointed out in the claim.

In the accompanying drawings, there is illustrated a central, longitudinal sectional View of a generator embodying the invention.

Referring to the drawing, 1 designates my generator which as illustrated herein serves to be `employed in connection with vapor lamps and it comprises a suitable length of metal tubing, at opposite ends and is adapted to extend above the lamp in a position so as to be acted on by the heat from the lamp.

The tube is provided with a lining 5, composed of asbestos or other suitable material and extends on the inner surface nearly the entire length of the same so as to provide a chamber 6 at one end of the tube and into this chamber is inserted a thimble 4 having a surrounding flange in which is arranged a screen 4, the flange serving to contact with the terminal of the chamber 6. A nut 2, having a cone shaped opening 6 therein which registers with an injector opening 3, whereby communication is had with the screen and thimble, and the nut engages the screwthreads on one end of the tube by means of which the hanged ortion of the thimble is clamped between t e nut and the terminal of the screw threaded end of the tube, whereby'to hold the thimble in proper position within the chamber 6.

` In practice, the lining which is not subject to the deleterious action of the acids conwhich is exteriorly threaded s tained in the hydrocarbon, will effectually protect the interior of the generator and prevent direct contact of the oil with the metal, thus obviating formation of the sediment as before explained, and will at the same time insure' a gradual heating of the interior of the vaporizer, thus` causing proper, gradual vaporization of the oil and insuring a consequent steady how of the vapor through the injector orifice 3. It will -be observed that by employing this form of lining within the generator the necessity for employing sand and other material within the generator is obviated and that in consequenee the device is adapted for aeeoinnodating1 e greater supply of hydrocarbon which may be fed slowly tlirougli the tube, thereby deriving the full action of the liet and insuring its proper and complete Conversion into vapor.

Having' thus fully described What I claim is:

A hydrocarbon oil vaporizer comprising' a metal tubing,r Witli oppositely disposed externally screw threaded ends, e lining Within the tubing', end extending nearly the length of the saine, a elia-inber formed between the end of the liningq and the end of the tube, a thimble inserted Within said chamber, said tliimble having a ilenge preiny invention,

i l l l l Sii-id nut serving to engage the screw tln'eznl` ed end ell tlie tube, so es to elznnp the llnnne of tlie thnnble esjsnnst the ternnnnl el' the tube and against tlie nut, substantially :is specified.

In teetnnony .vliereol', I nvtlix my signature in presence of two witnesses.
